== Personality == Newton has been described as an incredibly driven and disciplined man who dedicated his life to his work. He is known for having a prodigious appetite for work, which he prioritised above his personal health. Newton also maintained strict control over his physical appetites, being sparing with food and drink and becoming a vegetarian later in life. While Newton was a secretive and neurotic individual, he is not considered to have been psychotic or bipolar. He has been described as an "incredible polymath" who was "immensely versatile", with some of his first studies relating to a potential phonetic alphabet and universal language. Newton's diverse range of interests is seen in his library, which contained 1,752 books that could be identified. A large portion consisted of works on theology (27.2%, or 477 books), followed by alchemy (9.6%, 169 books), mathematics (7.2%, 126 books), physics (3.0%, 52 books), and finally astronomy (1.9%, 33 books). Ultimately, books related to his famous scientific work made up slightly less than 12% of the total collection. Although it was claimed that he was once engaged, Newton never married. Voltaire, who was in London at the time of Newton's funeral, said that he "was never sensible to any passion, was not subject to the common frailties of mankind, nor had any commerce with women—a circumstance which was assured me by the physician and surgeon who attended him in his last moments." Newton had a close friendship with the Swiss mathematician Nicolas Fatio de Duillier, whom he met in London around 1689; some of their correspondence has survived. Their relationship came to an abrupt and unexplained end in 1693, and at the same time Newton suffered a nervous breakdown, which included sending wild accusatory letters to his friends Samuel Pepys and John Locke. His note to the latter included the charge that Locke had endeavoured to "embroil" him with "woemen & by other means". Newton appeared to be relatively modest about his achievements, writing in a later memoir, "I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me." Nonetheless, he could be fiercely competitive and did on occasion hold grudges against his intellectual rivals, not abstaining from personal attacks when it suited him—a common trait found in many of his contemporaries. In a letter to Robert Hooke in February 1675, for instance, he confessed "If I have seen further it is by standing on the shoulders of giants." Some historians argued that this, written at a time when Newton and Hooke were disputing over optical discoveries, was an oblique attack on Hooke who was presumably short and hunchbacked, rather than (or in addition to) a statement of modesty. On the other hand, the widely known proverb about standing on the shoulders of giants, found in the 17th-century poet George Herbert's Jacula Prudentum (1651) among others, had as its main point that "a dwarf on a giant's shoulders sees farther of the two", and so in effect place Newton himself rather than Hooke as the 'dwarf' who saw farther.
== Theology ==
=== Religious views ===
Although born into an Anglican family, by his thirties Newton had developed unorthodox beliefs, with historian Stephen Snobelen labelling him a heretic. Despite this, Newton in his time was considered a knowledgeable and insightful theologian who was respected by his contemporaries, with Thomas Tenison, the then Archbishop of Canterbury, telling him "You know more divinity than all of us put together", and the philosopher John Locke describing him as "a very valuable man not onely for his wonderful skill in Mathematicks but in divinity too and his great knowledg in the Scriptures where in I know few his equals". By 1680, his reputation in biblical scholarship was established. John Mill sought his advice on a critical New Testament edition, and the two had a short correspondence on interpreting the early chapters of Genesis as well. Thomas Burnet consulted Newton on drafts of Telluris theoria sacra, and with Henry More he discussed the interpretation of the Apocalypse at Cambridge.
